Hi there, I am designing a product using an STM32H7RS-series MCU, and am looking for some clarification about the operation of the HSE oscillator. I see the H7RS has the option of an "analog" external oscillator in HSE bypass, in addition to the usual "digital" HSE bypass of previous products, and I am very interested in using that analog mode to use a lower voltage clipped sinewave output external oscillator, such as an NDK NT2016SE.
My question is do I need anything in series between the STM32H7RS OSC_IN pin and the output pin of the analog (clipped-sine in this case) TCXO? I would assume I'm not supposed to use a series capacitor like the datasheets of these oscillators tend to show, because the STM32H7RS appears to be looking for a DC-biased signal, but before I make a board with no provision for such an inline passive and find out it doesn't work I figured I should double check here.
Thanks!
